Preheat the oven to 440 F or 230 C and grease- or line a baking tray with parchment paper.
Chop up the jalapeños and bacon.
Cook the bacon in a saucepan for around 5-7 min or until it becomes crisp.
Drain the bacon, leaving it’s fat behind in the pan, and place on a paper towel to drain.
Fry the jalapeños for a couple minutes, and place with the bacon to cool.
Take out 1 tbsp of the flour and mix it with the cheese. Add in the cooled bacon-jalapeño mixture and stir to combine.
In a large bowl, combine the flour, baking powder, salt, sugar and butter and incorporated through a pastry cutter or fork until the mixture resembles breadcrumbs.
Whisk together the eggs and buttermilk, and add it into the flour mixture, stirring with a wooden spoon to combine.
Mix in the cheese mixture and place the dough on a floured surface. Knead for around 1 minute.
Spread the dough out into a circle 1 inch thick with your fingertips. Cut the dough into 8 equal portions using a pizza cutter.
Place the pieces of dough onto the baking tray. Brush with egg wash and sprinkle on some cheese.
Bake for 15-20 minutes or until the tops are golden in color.
Enjoy these nice and warm.
